View Source Debugging

It is possible to get debug logs from EctoWatch by setting the debug? option, either globally:

  # setup
  {EctoWatch,
   repo: MyApp.Repo,
   pub_sub: MyApp.PubSub,
   debug?: true
   watchers: [
     # ...
     {Comment, :deleted, extra_columns: [:post_id]},
     # ...
   ]}

Or on specific watchers:

  # setup
  {EctoWatch,
   repo: MyApp.Repo,
   pub_sub: MyApp.PubSub,
   watchers: [
     # ...
     {Comment, :deleted, debug?: true, extra_columns: [:post_id]},
     # ...
   ]}

Debug logs will be written to the :debug log level. They will output when:

• A watcher server is starting up
• A watcher server receives a message from PostgreSQL via a pg_notify channel
• A watcher server broadcasts a message to Phoenix.PubSub
• A process subscribes to a watcher

All debug logs have a PID associated as well as the identifier for the watcher server (either the label or a {ecto_schema, update_type} tuple).
